A tankless unit throwing error codes, failing to ignite, or delivering weaker hot water flow than it used to is often scale buildup on the heat exchanger, a clogged inlet filter, a flow sensor fault, or a venting problem rather than a failing unit. Hard water in Saint Charles, SD speeds up scale buildup, which is why units that go years without descaling tend to show these symptoms first.

If the unit is showing an error code, note it before calling since it narrows down the likely cause. Persistent ignition failures, a gas smell near the unit, or hot water that won't come up to temperature at all are reasons to stop troubleshooting and have someone look at the venting and gas supply directly.

Annual descaling is the single biggest factor in how long a tankless unit lasts. Call (844) 898-0295 and Smart Pro Plumbers will connect you with an independent local plumber in Saint Charles, SD to service it.

Tankless Water Heater Repair & Maintenance FAQs

Frequently asked questions about Tankless Water Heater Repair & Maintenance

Questions we hear most often about Tankless Water Heater Repair & Maintenance in Saint Charles, SD.

Talk to a real person
Why does my water heater's pilot light keep going out?
A pilot that won't stay lit is usually a failed thermocouple, the small sensor that tells the gas valve a flame is present. When it wears out, the valve shuts off the gas as a safety measure, even though you keep relighting it. Do not keep manually holding the pilot lit or forcing the gas valve. Shut the gas supply if you smell any odor and leave the area. This is a repair for a professional, not a DIY project. Call (844) 898-0295 and describe the symptoms to get connected with an independent local plumber.
Why is my water heater making popping or rumbling noises?
Popping, rumbling, or cracking sounds usually mean sediment has built up on the lower heating element or at the bottom of the tank. As water heats underneath that layer, it creates steam pockets that pop as they escape, and the trapped sediment makes the tank work harder and heat less efficiently. Hard water speeds up this kind of mineral buildup. It will not go away on its own and can shorten the tank's life. Call (844) 898-0295 and describe the noise to get connected with an independent local plumber who can inspect or flush the tank.
Why does my water heater's water get too hot then suddenly turn cold?
This pattern often points to a tripped high-limit reset switch, a safety device that cuts power to the heating elements if the water gets dangerously hot. It can be triggered by a failing thermostat or a bad element. On a gas unit, similar swings can come from a fouled burner or a failing thermocouple. Do not keep resetting the switch repeatedly. Turn off the water heater's power or gas supply and stop using hot water until it is looked at. Call (844) 898-0295 and describe what you are seeing.
Why is water dripping from the pipe on top of my water heater?
That pipe usually runs from the pressure relief valve, and a steady drip often means the valve is doing its job by releasing pressure that has nowhere else to go. A common cause is a failed expansion tank that no longer absorbs the extra pressure created when water heats up. Shut the cold supply valve on top of the tank if the dripping is heavy or the tank feels excessively hot. Do not ignore it, since pressure with nowhere to escape can be dangerous. Call (844) 898-0295 and describe what you are seeing in Saint Charles, SD.
My water bill jumped and I can't find a leak. What should I do?
Start by shutting off every fixture in the house, then check the water meter. If the dial is still moving, water is escaping somewhere, possibly underground, inside a wall, or under a slab, even if no puddle is visible. A running toilet or a small slab leak can waste a surprising amount of water without any obvious sign. Do not just wait for the next bill to see if it drops. Call (844) 898-0295 and describe what your meter is doing to get connected with an independent local plumber who handles leak detection in Saint Charles, SD.
